I've had this Aussie locker in my dana 30 for about 6 months now, it works perfectly, locking and unlocking as it's supposed to.
It was purchased on 8/10/10 for $250 and was installed by myself and Travis (mostly Travis).
I'm looking to get $200 for it, mostly because it's pretty much brand new and I have all of the original packaging and documentation.
If you're interested send me a text and we can work out a price (281) 787-0847
